The present disclosure describes an exemplary hybrid client/server architecture that may be utilized leverage the unique capabilities of both remote and local services. Data may be processed in parallel by remote and local processes. Results generated during the parallel processing may be exchanged between remote and local services and used to update results generated by the separate services. The hybrid client/server architecture may be utilized to generate enhanced inferences, hybrid subscriptions base upon local and remote subscriptions, and enhance natural language expression evaluation services.

Hybrid client/server architecture for parallel processing

Incorporation of an exogenous large-vocabulary model into rule-based speech recognition is provided. An audio stream is received by a local small-vocabulary rule-based speech recognition system (SVSRS), and is streamed to a large-vocabulary statistically-modeled speech recognition system (LVSRS). The SVSRS and LVSRS perform recognitions of the audio. If a portion of the audio is not recognized by the SVSRS, a rule is triggered that inserts a mark-up in the recognition result. The recognition result is sent to the LVSRS. If a mark-up is detected, recognition of a specified portion of the audio is performed. The LVSRS result is unified with the SVSRS result and sent as a hybrid response back to the SVSRS. If the hybrid-recognition rule is not triggered, an arbitration algorithm is evoked to determine whether the SVSRS or the LVSRS recognition has a lesser word error rate. The determined recognition is sent as a response to the SVSRS.

A voice command definition file (VCDF) declaratively defines voice commands for an application. For example, the VCDF may include definitions for: voice commands; one or more phrases/utterances that may be said to execute each of the commands; a navigation location to navigate to within the application (e.g. a page); phrase lists containing items that may be used as a parameter in a voice command; examples; feedback; and the like. A user may say a single utterance to launch the application, navigate to the associated location of the command and execute the command. The VCDF may define multiple ways to listen for a particular command. The VCDF may be edited/defined by a user and may include a user friendly name for an application. A speech engine loads the VCDF for use such that it may recognize the commands associated with an application. The definitions may be updated during runtime.
